Answer:
8 animal balloons
Step-by-step explanation:
Using equivalent ratios, or a proportion, you can solve for the number of animal balloons that clown can create in 6 minutes:
Now, set the simplified ratio equal to the time of 6 minutes and the variable of 'b' to equal the number of balloons:
![\frac{4}{3}=\frac{b}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%3D%5Cfrac%7Bb%7D%7B6%7D)
To get equivalent fractions, the numerator and denominator must be multiplied by the same factor:
![\frac{4x2}{3x2}=\frac{8}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B4x2%7D%7B3x2%7D%3D%5Cfrac%7B8%7D%7B6%7D)
8 animal balloons in 6 minutes
Answer:
9 feet
Step-by-step explanation:
Since it is a square, the length and width would be the same so the area would be a square number. Therefore, we can square root 81 feet, to get the answer of 9 feet.

Answer: $4.5 per copy
Step-by-step explanation:
1800 copies cost $8100
A copy will cost (Total cost ÷ Number of copies) = 8100÷1800 = $4.5 per unit copy
Given: PQ=2x-3. if QR=5x+7 and PR=10x-11
To Find: PR
Solution: From the attached diagram, point P, Q and R are co-linear.
Hence, PR = PQ + QR
or, 10x-11 = 2x-3 + 5x+7
or, 10x - 7x = 15
or, x = 5
Now, we shall calculate the value of PR
PR = 10x-11
or, PR = 10× 5 - 11
or, PR = 39
Hence, the required value of PR will be 39.
